Pneumatic conveying plant for sorting fruits and root crops

The article deals with the classification of sorting fruits and root crops. When reviewing existing structures, their shortcomings were identified. The authors proposed a new design of the sorting device. The basic principle of operation of this design is based on the creation of a suction air flow inside a metal pipe. The device consists of a container with unsorted fruit, a corrugated plastic pipe of variable length with a tip, a clamp attached to a square metal pipeline. Inside this pipeline there are three rectangular holes of different sizes equipped with gates are fixed. In the lower part of the adapters, cyclones with corrugated plastic pipes of variable length with tips are fixed, descending into the corresponding containers. A protective mesh is installed in the rear part of the metal pipeline and a fan housing is attached, inside which the fan itself is located, driven by an electric motor and creating a suction air flow. The proposed device makes it possible to simplify the design, reduce the consumption of materials, reduce energy consumption, reduce the labor intensity of maintenance, increase productivity, and reduce the degree of damage to the surfaces of sorted fruits and root crops.
